Specification of Letters Patent.

Patented May 31, 1921.

Application filed March 25, 1920. Serial No. 368,513.

To all whom it may concern:

Be it known that 1, CHARLES KAPPEL, a citizen of the United States, residing at Chicago, in the county of Cool: and State of Illinois, have invented new and useful Improvements in Ice-Cans, of which the following is a full, clear, and exact description.

My invention relates to metal receptacle for ice, and particularly to ice cans used in forming blocks of ice in ice manufacturing plants.

These cans are placed in vats in which cans of this'character, after they have been filled with water, are placed, and then liquid refrigerant is circulated around the cans until the water is frozen. Brine is usually employed as the refrigerant for this purpose, and it adheres to the under surface of and soon rusts and eats holes in the bottom of the can, and renders it useless until it is either repaired or replaced. The object of my invention is to overcome this objection in a comparatively simple and inexpensive manner, and to greatly extend the life of the can, substantially as hereinafter fully described and as particularly pointed out in the claims.

In the drawings:

Figure 1 is a perspective view of an ice can to which my improvements are applied.

Fig. 2 is a vertical transverse section of the same.

Fig. 3 is a plan view of the bottom of said can.

Fig. l is a perspective view of a disk used in connection therewith. v

Referring to the drawings A represents the sides of an open top can which is, preferably, rectangular in cross-section and tapers slightly from its bottom to its top edges. The top edges are reinforced by a metal strip a secured in any suitable manner to the exterior of the upper margins thereof, and holes 7), are made in the center of length of two opposite and parallel strips to facilitate lifting the cans out of or replacing them in the vat. At its lower end the can is provided with a double bottom, that is with an upper or false bottom B, whose edges are bent downward to provide flanges 0 that are secured by rivets (Z or other suitablemeans to the sides of the can, and below this the real bottom C whose edges are likewise bent downward to provide flange e that are also secured by rivets f to the sides of the can. The lower of these bottoms C, is spaced apart from the upper bottom by hearing against the lower edges of the flanges c of the upper bottom and thus provides a space or chamber that is filled with tar E or other suitable insulating material.

in order to introduce the tar into the space between the two bottoms, the lower, C, 1S provided with one or more perforations F. I prefer to use two of said perforations and when filling said space the can is turned upside-down and the liquid or melted tar is poured into the same through one of said perforations and, as it fills up, the air escapes out through the other perforation. After the tar has completely filled said space or chamber the two perforations are sealed by means of metal plates or disks G, substan tially as shown in the drawings. 1

Should either of said bottoms have holes eaten in them by rust or otherwise, these holes can be soldered or patched over, and the said bottom heated so as to soften the tar and permit it to flow into the rust holes and coat the edges of the same in such manner as to stop further corrosion. The introduction of tar into the space between said upper and lower bottoms doubles the life of the can, because the inner or upper bottom only comes in contact with the fresh water and lasts about twice as long as the lower bottom, which latter is subjected to the action of the brine. With ordinary care, by soldering and repairing the corroded metal of said bottom, the can should last three or four times as long as those heretofore in use.

One of the great advantages resulting from the use of my improved ice can is that the water freezes from the circumference of the can toward the center and not from the bottom upward, and thus eliminates the core of air-bubbles now universally resulting from the ice freezing cans now in use in artificial ice plants.

What I claim as new is:

1. in an icocan, a body having side walls and a double bottom comprising upper and lower spaced plates, the lower plate having a plurality of openings therein through which is introduced a plastic heat insulating material in liquid state to completely fill the space between said bottoms, and means for sealing said openings.

, 2. in an ice can, a body having side walls and a pair of bottom plates therefor, in spaced relation to form a compartment and secured to said side walls, and a heat insulating non-metallic composition introduced between said plates and completely filling the compartment formed thereby. t

3. In an ice can a body having side walls and a pair of bottom plates therefor, in spaced relation to form a compartment and secured to said side walls, a heat insulating non-metallic composition introduced between said plates and completely filling the compartment formed thereby the lower plate having a plurality of openings therein for the introduction of said composition, and means for sealing said openings.

4. In an ice can a rectangular body in cluding tapered side walls double bottoms in said body having downturned marginal flanges fitting snugly in said body, the flanges of the upper bottom resting upon the lower body, and serving to separate said bottoms and provide a space therebetween, the lower bottom having a plurality of openings therein for the introduction of a nonmetallic filler in liquid form, to completely fill said space and set therein and closures for said openings.

In witness whereof I have hereunto set my hand this 23d day of March, 1920. CHARLES KAPPE WVitnesses:
